The alkaline single cell gel electrophoresis (comet) assay was used to clarify in vitro and in vivo genotoxicity of 2-bromopropane (2-BP). For in vitro studies, fresh medium containing 2-BP (2.50, 1.00, 0.50, 0.25, 0.10, 0.05, 0.01 mM, and vehicle control) were added in human lymphocytes.(omitted)

Objectives: The major objectives of this study are to review the requirements for the advancement of occupational safety and health administrative organization and to propose measures to establish an Occupational Safety and Health Executive. Methods: The problems of occupational safety and health administrative organization in korea were examined empirically and cases of occupational safety and health administrative organizations in developed countries were investigated (United Kingdom, United States, Germany, and Japan). A plan for establishing an Occupational Safety and Health Executive was proposed over the short and medium term. Results: An occupational safety and health administration is characterized by a professional and technical nature, and even more so in modern society. Therefore the greatest value required by an occupational safety and health administrative organization is expertise. In addition, administrative values it requires include efficiency, specificity, independence, and activity. The Korean occupational safety and health administrative organization has a number of problems in terms of these values. The most appropriate way to realize these values is to establish an Occupational Safety and Health Executive. It is desirable to establish such an Occupational Safety and Health Executive in a phased manner taking into consideration its relationship with Korea Occupational Safety and Health Agency(KOSHA), including KOSHA's functional adjustment Conclusions: In order to solve the deep-seated problems in occupational safety and health administrative organization and to advance occupational safety and health administration in Korea, it is necessary to establish an Occupational Safety and Health Executive as a foundation for achieving an advanced industrial safety and health administration.

This brief report aims to establish the keyword content of studies on occupational health and safety-the key framework of the world of work in the trade and health domain. Data were collected from the SCOPUS database, focusing on articles on occupational health and safety and related keywords, with an emphasis on abstracts and titles. Data were analyzed and summarized based on keywords included from the MeSH database. There were 24,499 manuscripts in the domain and 1,346 (5.40%) occupational health-related keywords, including those that overlapped. The most frequently referenced occupational health-related keyword was "occupational health" (452 articles), followed by "occupational safety" (141 articles). There were fewer keywords on occupational health in the trade and health literature. As the world of work has been prioritized because of the recent new normal of work life since the COVID-19 pandemic, examining the focus of occupational health priorities within the global perspective is crucial.

Background: Occupational Health and Safety Management Systems are becoming more widespread in organizations. Consequently, their effectiveness has become a core topic for researchers. This paper evaluates the performance of the Occupational Health and Safety Assessment Series 18001 specification in certified companies in Iran. Methods: The evaluation is based on a comparison of specific criteria and indictors related to occupational health and safety management practices in three certified and three noncertified companies. Results: Findings indicate that the performance of certified companies with respect to occupational health and safety management practices is significantly better than that of noncertified companies. Conclusion: Occupational Health and Safety Assessment Series 18001-certified companies have a better level of occupational health and safety; this supports the argument that Occupational Health and Safety Management Systems play an important strategic role in health and safety in the workplace.

Background: Safety climate and occupational stress are related with occupational accident. The present study tried to identify the differences in safety climate and occupational stress according to occupational accidents experience and employment type (e.g., direct workers and subcontract workers). Methods: In this study, we conducted a survey using safety climate scale and Korean Occupational Stress Scale and classified the participants into four groups: direct workers working for accident-free departments, direct workers working for accident departments, subcontract workers working for accident-free departments, and subcontract workers working for accident departments for 2 years within the same workplace in the shipbuilding industry. Results: The direct workers and subcontract workers showed diverse results in subscales of safety climate and occupational stress. This result is supported by existing studies; however, further study is necessary for more supporting evidence and elaborative methodological approach. Conclusion: The necessity of management for safety climate and psychosocial factor such as occupational stress for both direct workers and subcontract workers as a whole is suggested by this study.

Objectives: This study was conducted in order to obtain information concerning the health hazards that may result from a 13 week inhalation exposure of n-pentane in Sprague-Dawley rats. Methods: This study was conducted in accordance with the Organization for Economic Co-operation and Development (OECD) guidelines for the testing of chemicals No. 413 'Subchronic inhalation toxicity: 90-day study (as revised in 2009)'. The rats were divided into 4 groups (10 male and 10 female rats in each group), and were exposed to 0, 340, 1,530, and 6,885 ppm n-pentane in each exposure chamber for 6 hour/day, 5 days/week, for 13 weeks. All of the rats were sacrificed at the end of the treatment period. During the test period, clinical signs, mortality, body weights, food consumption, ophthalmoscopy, locomotion activity, urinalysis, hematology, serum biochemistry, gross findings, organ weights, and histopathology were assessed. Results: During the period of testing, there were no treatment related effects on the clinical findings, body weight, food consumption, ophthalmoscopy, urinalysis, hematology, serum biochemistry, gross findings, relative organ weight, and histopathological findings. Conclusion: The no-observable-adverse-effect level (NOAEL) of n-pentane is evaluated as being more than 6,885 ppm (20.3 mg/L) in both male and female rats. n-pentane was not a classified specific target organ toxicity in the globally harmonized classification system (GHS).
